SPECIFICATION forming part of Letters Patent No. 738,280, dated September 8, 1903.

Application filed March 16, 1903- Serial No. 148,117. (No model.)

To all whont it may concern:

Be it known that W6,WILLIAM EDGAR BELL and FRANoIs WILLIAM BROWN, citizens of the United States, residing at Devine, in the county of Medina and State of Texas, have invented a new and useful Look, of which the following is a specification.

This invention relates to looks which are applicable to a variety of purposes-such as, for instance, to house-doors, outside doors, inner safe-doors, and the like; and it has for its object to provide a lock which shall be simple in construction, easily operated, not liable to get out of order, not capable of being picked or of being operated by persons not having some knowledge of the mode of operating the look and which, generally speaking, shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these ends in view our invention consists in the improved construction, arrangernent, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan View of our improved lock, the front plate having been removed to' expose the interior construction and the lock being shown in locked position. Fig. 2 is a vertical sectional View of the lock complete. Fig. 3 is a perspective view showing in detail the several parts or members combined in the makeup of the lock. Fig. 4. is a detail view of the key. Fig. 5 is a part sectional detail view of one of the latch knobs. Fig. 6 is a sectional detail view. of a door-bolting device used in connection with and cooperating with ouriinproved lock. Fig. 7 is an elevation showing the lock applied to adouble door.-

Oorrcsponding parts in the several figures are indicatedby similar numerals of reference.

1 designates the casing of our improved lock, which is preferably rectangular, as shown, and which is provided with a raised flange 2, against which the front plate 3 may be fitted when the parts of the device are assembled. The back plate 4: of the lock-casing and the front plate 3 are each provided v with a centrally-disposed outwardly-extending boss, the one upon the back plate being designated 5 and the one upon the front plate 6. Each of these bosses is provided with a circular aperture 7, having an internal'annular flange 8, which serves to retain and to guide the lock-barrel, as will be presently described.

9 designates the lock-barrel, which is provided near one end with a disk 10, having on its outer side an annular rabbet 11, which engages against the inner side of the annular flange S of the back plate of the'lock. Both ends of the barrel are screw-threaded, and said barrel is provided .at the ends thereof with slots 12 and 13, the slot 12 at the rear end of the barrel being extended through the disk 10, as will be seen at 14, thus forming a keyhole of suitable dimensions. Thebarrel is itself longitudinally perforated for the passage of the key.

15 designates a disk which corresponds in size and shape with the disk 10 upon the bar rel, it being provided with an annular rab= bet 16, adapted to bear against the annular flange 8 of the back of the look. This disk 15 has a central screw-threaded perforation 17, whereby it, is adjusted upon the rear end of the barrel until the slot 14 in the disk 10 is in alinement with a corresponding slot 18 in the disk 15. The disks 10 and 15 are then securely connected by means of screws 19, in sorted through alining perforations in said disks, which are thereby connected revolubly with the flange.

j 20designates the bolt-operating disk, which v This disk is also provided with slots 22, corresponding with the slots 14 and 18 in the disks 10 and engage the circular apertures in the back and front plates of the lock-case, respectively. Said disk is furthermore provided with circular recesses 24, one at each end, adapted to receive the loose or floating plates 25, which are placed loosely and revolubly in the said recesses and which are provided each with a central opening 26 to engage the lockbarrel and with a slot 27, corresponding with the slots 14:, 18, and 22. The said disk 20 is This disk 20 is provided ateach end thereof with annular rabbets 23, adapted to :is centrally perforated, as at 21,. to enable it to be placed upon the lock-barrel.

furthermore provided at diametrically opposite sides with recesses 28',in which the ends of upward and downwardpxtending pitmen or connecting-rods 29 are pivotally mounted upon transverse pivot-pins 30. These recesses 28 may be described as being at the upper and lower edges of the disk 20. Intermediately between said recesses is formed a similar recess 31, in which the lock-bolt 32 is pivotally mounted upon a pin 33, the flange of the lock-case having a slot 32 for the passage of said bolt. The edge of the disk opposite to that having the recess 31 is provided with a peripheral groove 34, constituting a slide-race and terminating in recesses 35 and 36, which are disposed at the other ends of the keyhole-slots 22.

37 designates a slide secured upon and in contact with the back-plate of the look by means of a keeper 38, a spring 39, bearing against the flange of the lock-case, serving to normally force the said slide in an inward direction toward the disk or plate 20 and into the slide-race 34 with one of the recesses 35 and 36, of which it is normally in engagement. The inner engaging end of this slide is beveled or tapered, as will be seen at 40, and said slide is obviously made of such a shape that it will not turn in its keeper or socket, thereby insuring the presentation of the beveled end at all times in the properdirection. The flange 2 of the lock-case is provided at the top and bottom thereof with perforations 41 for the passage of bolts 42, the inner ends of which are pivotally connected with the-outer-ends of the pitmen 29, the inner ends of which have pivotal connection with the recesses 28 in the disks by means of the, pins 30, hcreinbefore described. The outer ends of the bolts 42 are screw-threaded for convenient connection with extensionbolts 42, adapted to engage keepers at the top and bottom casing of the door to which the lock is applied. It is obvious that by partly turning the disk 20 the bolts 32 and 42 may be withdrawn or extended, as may be required, for the purpose of opening or closing the lock, which is retained in its opened or closed position by means of the slide 37, engaging one of the recesses 35 or 36. The connecting groove between said recesses forms what we term a slide-race, which enables the disk to be partially turned when the slide 37 is withdrawn, as will be readily understood.

A disk 43 of identical construction with the disk is screwed upon the outer end of the barrel 9, thereby retaining the disk and its related parts in position in such a manner as to permit it to revolve freely. The front plate 3 is then mounted in position and connected with the lock-case by means of suitably-disposed screws or fastening means, and a disk 44, corresponding with the disk 43, is finally screwed in position upon the extreme front end of the barrel and is connected with the disk 43 by means of fastening'screws 45.

It will thus be seen that the disks 43 and 44 are placed rotatably in engagement with the flange 8 of the front plate in like manner as the disks 10 and 15 engage the flange 8 of the rear plate. It is also obvious that said disks, owing to the construction set forth, are all connected with and revolve with the central barrel 9, while the floating plates are revoluble independently of the remaining parts of the lock.

A latch 46 of ordinary construction is provided, said latch being actuated by means of a spring 47, suitably secured within the lockcases and said latch being operated by means of wings 48 upon a stem 49, extending through the lock-case and provided with screw-threaded ends 50, upon which the handles 51 are mounted and secured in the usual manner by means of set-screws 52.

In operation when the lock is bolted the slide 37 is in engagement with the recess of the bolt-operating disk 20, the position of which, as indicated in Fig. 1, will be such that the bolts 32 and 42 will be shot or extended. The key which is used in connection with this look is provided with a central guide-rib 53 and a bit 54, provided with an angular or tapering corner 55. When said key is inserted into the keyhole from either side, the lock-barrel may be turned until the keyhole-slots pass into alinement with the corresponding slot in the adjacent floating disk 25. The latter will now turn with the key until the beveled or angular corner of the bit of said key passes into alinement with the recess 35, into which the beveled end of the slide 37 projects. Pressure upon the key will now still farther insert the latter into the lock until the end of theslide 37 becomes disengaged from the recess 35, when it will offer no obstruction to the turning of the operating-disk to the position indicated in dotted lines in Fig. 1, when the said slide 37 will engage the recess 36, and thus retain the locking-disk in position,with the bolts withdrawn to an unlocked position. In the act of withdrawing the key from the lock the position of the various movable elements may be readily disturbed, so that the key may not be readily inserted into the lock for the purpose of operating the same without a practical knowledge as to how the operation is to be performed.

It has been stated that the bolts 42, extending upwardly and downwardly from the lock, shall be provided with extensions 42, reaching to the top and bottom of the door-casing,

where suitable keepers are to be provided to be engaged by said bolts, as will be readily understood.

When the look, as illustrated in Fig. 7 of the drawings, is applied to a double door, we provide an additional fastening means comprising a plate 53, which is secured to the top of the door-casing and which is provided with guides or keepers 54 55 for a pair of vertically-slidable short bolts 56 and 57, the upper ends of which are provided with pins 58, engaging slots at the outer ends of the arms of a bell-crank lever 60, which is pivotally connected with the plate 53. The slide 57 is normally kept in a raised position by means of a spring 61, interposed between its upper end and the top of the keeper 55, in which it is vertically movable, thus keeping the slide 56 normally,in a depressed position, as will be seen in Fig. 6 of the drawings. The doorsection 62, to which the lock is attached, is provided at its upper end with a keeper 63 for the eXtension-bo1t42, said keeper being, when the door is closed, in alinement with the keeper 54. It is obvious that when the door is closed and the lock is bolted the boltsection 42 will force the sliding member 56 upwardly against the tension of the spring 61, thus depressing the sliding member 57 through its housing and into a keeper 64 at the upper end of the doorsection 65. Both door-sections 62 and 65 will thus be securely bolted by the action of the single lock.

We desire it to be understood that while we have in the foregoing described a'simple and preferred construction of our improved lock we do not thereby limit ourselves to the precise structure herein set forth, but reserve to ourselves the right to any changes, alterations, or modifications which may be resorted to within the scope of our invention and without departing from the spirit or sacrificing the utility of the same.
